The technology that I most often use is a cellular phone. I always use it and it is necessary and indispensable to live. The merit of the cellular phone is a thing that can always be contacted the person.And it is possible to communicate with every person by the use of various networks , for instance, mixi,twitter,and skype etc.The disadvantage is a thing felt uneasy if the cellular phone is not at hand.So,it is thought that a recent technology is very convenient,but I like good old days better than high-tech ages.
